Just a note, if you have a ride that is very old i.e. 70's or earlier, the question of whether you will develop leaks due to the use of rubber seals and the like may be valid, as Fossil says,.
But never rely on "varnish and sludge" to keep liquids inside. Probably the same person who invented that also says never change your oil, there is enough blowby and burning that simple refill at the proper level should last a lifetime...same thing as the toilet paper bypass oil filter design, "--did I use Scott single ply or Charm'in double ply...?:bigsmiley22:
A fair amount of bikes may be old vintage on the outside, but have modified internals w/ modern seals made out of neoprene or other plastic based materials that are much more resilient and tolerate modern oil additives, in the event they are rebuilt with modern components. So that one size fits all approach does not necessarily apply. Only way to be sure is to learn from HDT forums like this, from posters with similar situations and experiences like you. Learning and knowledge is power...
